Weekend Weather Planner: High Heat and Humidity with Storm Chances

Updated: 7:06 PM EDT Jul 17, 2026 — WLKY News (Louisville, Ky.)

What’s Happening Right Now (Friday Evening)

Imagine the air outside feels like a warm, wet blanket. That’s what “hot and humid” means!

• Right now it is 88°F, but because the air is so sticky (humid), it feels like the middle to upper 90s—almost 100°F in many spots.
• A heavy rain shower (called a “pulse shower”) popped up near the airport and Ottoman Park. It’s coming down hard and may have a gust of wind.
• More rainy spots are showing up southwest of the city (St. Matthews, Briarwood) and in nearby counties (Mount Washington, Spencer, Nelson, Jackson, Litchfield).
• No severe weather warnings are in effect—these storms aren’t organized enough to be dangerous, but they can dump a lot of rain locally.

Important: No severe warnings right now, but carry an umbrella if you go out Friday evening—it’s unsettled and spotty showers/storms may surprise you.

Friday Night Plan

• Scattered showers and storms this evening will slowly fade as the night goes on (the atmosphere loses its “instability,” meaning the air calms down).
• It stays warm and humid, dropping only to the middle/upper 70s overnight.

Saturday: Hot, Then Stormy at Night

1. During the day: Lots of dry time! Mix of sun and clouds.
2. Temperature: High near 91°F, feeling close to 100°F (especially in southern Indiana farm fields where plants release moisture).
3. Evening/night: A weak “cold front” (a line of cooler, drier air) slides in from the north.
4. Result: Scattered showers and storms for Saturday night.
5. Watch out: A few storms could be strong—with gusty winds, lightning, and heavy rain.

Callout: Saturday night storms may bring strong wind gusts. Keep an eye on the sky if you’re out!

Sunday: A Little Relief

• Storms leave before sunrise (predawn hours).
• Heat and humidity briefly step down—a nicer end to the weekend.
• In the Louisville metro, Sunday stays mostly dry; storm chances shift to downstate Kentucky in the afternoon.

The Bigger Picture (4‑Day & 7‑Day)

• Monday–Tuesday: Hot and humid again (low 90s).
• Tuesday: Another cold front brings impact weather—scattered showers/storms Tuesday afternoon/evening.
• Wednesday–Friday: Finally a break! Highs drop to low/mid 80s with less humid air.
• Bonus: Mold count (which bothers allergies) will come down after the front—goodbye sneezes!

Summary

This weekend brings classic summer weather: hot, humid days with pop‑up storms. Friday night has spotty showers; Saturday is dry and hot by day but stormy at night (a few strong); Sunday calms down briefly. By mid‑next week, a front cools us off for real. Pack umbrellas, drink water, and enjoy the weekend!

FAQ

Q1: What does “feels like 100°F” mean?
A: It’s the “heat index”—when humidity is high, sweat can’t cool you, so the air feels hotter than the thermometer says.

Q2: Is severe weather expected?
A: Not Friday. Saturday night storms could be strong (wind/lightning/heavy rain), but no warnings are out yet.

Q3: Will the whole weekend be rainy?
A: No! Saturday daytime is mostly dry, and Sunday is dry in Louisville. Only spots get storms.

Q4: When will it stop being so muggy?
A: After the Tuesday front—Wednesday through Friday will feel less humid and cooler.

Q5: Why mention mold count?
A: High humidity feeds mold, which triggers allergies. Less humidity next week = lower mold = easier breathing.
